<<Disclaimer: Verify this information before applying it to your situation.>> Hi List: Smith Kline stated that Aquafresh may contain trace amounts of gluten due to the raw ingredients they receive from their suppliers. Has anyone had any symptoms with Aquafresh? (My 3 year old celiac son has had a tummy ache for a couple weeks & I'm trying to figure out if it's gluten related.) Thank you. Wendy, Exton, PA
